-
When connecting components that are sensitive to polarity, such as LEDS and
the TTL Power MOSFET.
I/O Modules
•
Use the correct Input or Output port as required for each module.
-
Vibration Motor – supported on
OUT 1
,
OUT 2
, and
OUT 3
.
-
Servo Motor – use
OUT 3
only.
-
White LED – supported on
OUT 1
,
OUT 2
, and
OUT 3
.
-
Analog Light Sensor – supported on
IN 1
,
In 2
, and
IN 3
.
-
Ultrasonic Ranger – supported on
IN 1
,
IN 2
.
•
Use an Auxiliary Power Source for modules that require more than 50 mA,
including:
-
Vibration Motor
-
Servo Motor
•
Do not hold the Servo Motor’s shaft while it is rotating. Also, do not rotate the
Servo Motor by hand.
•
White LED:
-
Do not bend the leads repeatedly; this will weaken the wires and may cause
them to break.
-
The LED requires the correct polarity when inserted into its socket. For details,
refer to the instructions for assembling the LED in the TI-Innovator™
Technology eGuide (page ii).
-
The LED requires the correct polarity when inserted into its socket. For details,
refer to the instructions for assembling the LED (here).
•
No I/O module can sink or source greater than 4 mA.
TI-Innovator™ Rover
•
Do not expose the Rover to temperatures above 140
˚
F (60
˚
C).
•
Do not disassemble or mistreat the Rover.
•
Do not put anything heavier than 1 Kg or 2.2 lbs on the Rover platform.
•
Use only the USB cables provided with the TI-Innovator™ Hub.
•
Use only the Ribbon cables provided with the Rover.
•
Use only the TI provided wall charger included with the Hub.
•
The front-mounted Ultrasonic Ranger will detect objects within 4 meters of the
Rover. For best results make sure the object's surface is bigger than a folder. If
used to detect small objects, such as a cup, place the Rover within 1 meter of the
object.
•
For best results, leave the Slide Case off of your graphing calculator.
•
For best performance, use Rover on the floor, not on tables. Damage may occur
from Rover falling off a table.
